How it worksPaste JSON and it renders as an interactive mind map: click nodes to fold / unfold subtrees, scroll to zoom, drag to pan. Keys and values are shown as-is — a pure structural map, no AI rewriting. Very large data is truncated to stay smooth.

Why use this JSON mind map tool

Structure becomes a map

Nested JSON turns into a radial mind map where the hierarchy is obvious — explain a data structure without drawing diagrams by hand.

Explore interactively

Click to fold or unfold subtrees, zoom with the wheel, drag to pan, refit with one click — even large structures stay navigable.

Values and counts inline

Leaves show their values and containers show child counts; toggle to keys-only for a structure-first view.

Pure structure, no AI

No summarizing, no rewriting — your keys and values appear exactly as they are, ready for documentation screenshots.

Local & private

Data is rendered entirely in your browser — never uploaded, never stored.
